Vitamin C and Aging

Newsmax reports:
Researchers studied 655 elderly Japanese women, who did not take supplements, to ascertain how vitamin C levels affect strength, balance, and overall fitness. The study, reported in the September 20, 2011, issue of the Journals of Gerontology Series A: Biological Sciences and Medical Sciences, examined physical performance, lifestyle, and plasma vitamin C concentrations of the subjects.

This study positively correlated vitamin C levels with strength, agility, and walking speed — all of which are important measures of aging. The authors found plasma vitamin C concentrations positively correlated with handgrip strength, length of time standing on one leg with eyes open, and walking speed.
